[QUOTE="HoLeChit, post: 4058123, member: 35036"] Looking at your picture I see a vent in your siding, and it appears that there’s soffit vents, at least one next to your chimney? I would make sure that neither of them are blocked, and would definitely consider adding a fan to the wall vent in your siding. Maybe throw a few of those rigid foil backed foam boards up in between your rafters to block some of that heat from the deck. I wouldn’t make a complete seal or anything, but if you can cover 80% of the affected gaps with foam board wedges in, then you’ll have that much less radiant heat and still have room for your house to breathe as it was intended. Yeah, radiant heat sucks, but if you have an air gap between your rafters and your insulation/house framing, then most of your heat problems will likely be coming from the trapped air in your attic. Some of that heat in the top corners of your room will be unavoidable, as that’s where your roof comes in contact with your walls, and creates a thermal bridge. [/QUOTE]
